Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for creating bioactive molecules due to its piperazine core, which is commonly found in drugs with antipsychotic, antidepressant, or anxiolytic activity. Its bromoaryl group allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry research and drug discovery. Also utilized in the preparation of receptor ligands for biochemical studies.
